This invention relates to I an improved scrubbing device adapted forscrubbing and cleaning metal, glassand other surfaces to remove foreignmatter adhering thereto.

5 One object of the present invention is to provide a device of thischaracter adapted for use in cleaning metal, glass and other surfaceswhich is of a convenient shape for use in scrubbing and which is madeentirely or substantially throughout of abrasive material whereby itwill not becomeinefi'ective for the purpose through the elimination ofthe abrasive portion'by reason of wear. 7 I V A further object is thatofproviding an article of this character capable of being readily andeconomically constructed and which will eificiently accomplish thepurposes for which it is provided. g lVith these and further objects inmind reference is had to, the annexed specification taken in connectionwith the drawings, which latter illustrate one practical embodiment oftheinvention and in which w Figure 1 is an elevational view or a tubularbraided wire fabric, a portion-thereof being shown in expandedcondition, together with a mandrel or former which may be employedfabric forming the pa-d maybe of greater in expanding the wire meshfabric.

Fig. 2 1s a vertical sectional view of a portion of a tubular wire meshfabric having one end thereof stitched together to form a sheath. v I

Fig. 5 is a perspective View of the complet- 49 ed device.

1n the embodiment of the invention illustrated herewith l designates atubular metallic braid formed of metal strands'or threads 2 which ismade as a fiat braidbut which may be exp andcd to separate thethreads orstrands with angular edges=5 which-are adapted to exert an abrasiveaction upon surfaces to be cleaned when the threads have been separatedfrom each other after the manner described.

I propose to utilize the expanded tubular wire mesh, formed as abovedescribed, in'the of awire, thread or ordinary cord and then "reversingthe tubular section '6 to bring the stitching 7 within the sheath thusforminga sheath 8 for the receptionof a suitable filler material forwhich Imay employ apad 9 constructed as will be more fully describedhereinafter, although variousother kinds and arrangeme'nts of fillermaterial may be employed in forming the .pad as will be apparent 7 0 tothose skilled in the art.

Thepad 9, like the sheath 8, is formed in the present illustratedembodiment of the invention from a, tubular expanded wire meshconstructed after-the manner shown in 1 Fig. 1 of the' drawings.

The-sectionof expanded tubular wire mesh length than the section formingthe sheath 8 and theopen ends thereof are secured together as bystitches or loops 10, and wires or cords 11 located withinthe pad areemployed to drawtheopposite ends ofthe tubular section towards each;other and thus form folds 12 in the pad as the fabric material is foldedupon itself to increase thebulk of thePad.

In assembling the parts to form the completed devicethe padSis insertedwithin the sheath .8and theends of the cords or wires 11 are secured tothe stitched ends of the sheath so ;by means of .links'or stitchesl l asshown in Figia I The edgeof the tubular material ad- 'jacentto theopenend of the sheath is inturned and stitchedtogether-as indicated at 15 toclosethe end of the sheath and form as the completed scrubbing device.16. The

cord-s or wires 11 hold the pad :9 against'ex-L Ipansion asshown, and,whenthe ends of the wires are securedito. the ends of thesheath bystitches 14s the wiresllprevent longitudinal ing the end of thecomposite sheath.

expansion of the sheath which with braided tubular fabric as shown wouldresult in de creasing the diameter of the sheath and thus altering theshape of the completed structure. WVhilc I have shown the sheath 8 asbeing formed of a single section of the expanded tubular wire meshfabric, I may employ two or more sections telescoped one within theother and with a common stitching for clos- In like manner I may employa plurality of tubular sections telescoped one within the other informing the pad 9, or if desired the padinay be formed by flattening asection of the tubular wire mesh fabric and folding the flattenedmaterialupon itself to a suliicient extent to produce a pad of thedesired thickness.

WVhile I have described above a preferred form of my invention I mayform the pad 9 partially of metallic wire mesh and partially of cloth orother suitable filler material, such, for example, as woven or unwovenmetal strands or threads, orI may form the pad entirely of unwoven metalstrands, threads, or

other suitable abrasive material prepared in any desired manner withoutdepartlngfrom the spirit and scope of my invention as defined by theappended claims. 7

It is to be understood also that the cords or wires 11 employed forholding theparts from undue expansion. may be of any desired numher, andmay in certain cases, as where flatly folded tubular Woven metal fabricmaterial is employed in forming the pad, be connected with the oppositeends of the sheath, and may or may not be operatively connected with theends of the pad.

WVhat I claim is:

1. A scrubbing device comprising a pad of abrasive material, a covertherefor comprising a section of stretched wire mesh fabric arranged inthe form of a tube over said pad,

and means connecting opposite ends ofsaid tube to limit the expansion ofthe same longitudinally.

: i 2. A scouring device including a tube of resilient material disposedin the form of corrugat ons, means associated with said tube "formaintaining such corrugations, and a maintaining such corrugations, anda sheath of flexible metal-fabric enveloping such pad andhaving its endsclosed to retain the same.

4. A scouring device including a tube of resilient material disposedinlthe form of corrugations, means associated with said tube formaintaining such corrugations, and a sheath of fiemble metal fabricenveloping such pad and having its ends closed to retain the same, andmeans associated with nature.
